Humidity sensors
and probes need regular re-calibration to ensure continued accuracy.
In many cases these must be sent away to a certified calibration
laboratory, which may be effective but is rarely convenient as
there will be significant process downtime.

The S503 from
Michell Instruments means that field calibration of RH sensors
and humidity probes is affordable, practical and extremely flexible
for any company that uses RH instruments.

The S503 humidity
calibrator from Michell Instruments is:

Small and light:
At under 2kg in weight and 24cm wide, the instrument is portable,
very compact and comes with a convenient carry case.

Reliable: Michell
Instruments have 35 years experience in moisture calibration
and sensing. The S503 provides exceptional thermal stability
to better than 0.1°C. In combination with a Michell Chilled
Mirror Hygrometer, such as the Optidew Vision, you can create
a complete traceable humidity calibration system. This feature
is unique to the market.

Simple to use:
The S503 can be used by all staff as no specialist training or
experience is necessary. The calibration chamber can calibrate
up to 7 probes at once helping to save time as well as money.
